Abstract

A well-founded and computationally fast method is presented for filtering
and interpolating noisy and discontinuous wrapped phase fields that preserves
both the 2π discontinuities that come from the wrapping effect and the true
discontinuities that may be present. It also permits the incorporation of
an associated quality map, if it is available, in a natural way. Examples
of its application to the computation of the isoclinic phase from photoelastic
data and to the recovery of discontinuous phase fields from speckle interferometry
are presented.
